I have a mass flow rate, an area for the pipe and thus the diameter. I need to know the length of the pipe, but I end up with one equation and 2 unknowns. Is it possible to use the mass flow rate to somehow find the volume, which, in turn I can use to calculate the length? Or, any other...

I have tried the internet, but must have missed this one...thank you so much!

Does anyone know where I might be able to find the specific heat capacity of steel (in English units)? Thank you!

The way the costing was described to me was like this: "How much does a new truck cost?" Which is more believable: $40,000 or $1? I just need my teacher to believe my cost estimates. This whole costing estimate part of the project is just a little over my head...a bit overwhelming if you will...

I know - trust me - it is tough! What I have done so far is a superheat and reheat cycle. My maximum T is 950 degrees F and it works between the pressures of 1 psia and 2500 psia, with a reheat pressure of 400 psia. This gave me a cycle efficiency of 38% and this is the closest I've been. I've...

I am trying to come up with a design for a steam power cycle with a 40% thermal efficiency under the conditions that all turbines have isentropic efficiencies of 85% and all pumps have isentropic efficiencies of 60%. I have tried superheat, reheat, playing around with pressures/temperatures...

Having some troubles designing a steam power cycle for a project - any experts that would be willing to assist and offer some advice? Any help would be greatly appreciated! Thank you.

Homework Statement I have a project for a class of mine that asks me to design a rankine cycle to produce electricity from a lake using temperature differences between the water and the atmosphere. I have a budget that I must stick with ($40,000), a defined effeciency for the pump (50%)...
